  • the method includes receiving from the others of the plurality of client stations 120 data indicative of a detected sound levels during the one or more predetermined times.
  • the method includes associating the data indicative of the sound levels with a location within each of the zones 140 of the one or more of the plurality of client stations 120 instructed to emit a test signal at a respective one or more predetermined times.
  • the method includes calibrating the sound map automatically while the alarm system is in an armed-away state.
  • embodiments can be in the form of processor- implemented processes and devices for practicing those processes, such as a processor.
  • Embodiments can also be in the form of computer program code containing instructions embodied in tangible media, such as network cloud storage, SD cards, flash drives, floppy diskettes, CD ROMs, hard drives, or any other computer-readable storage medium, wherein, when the computer program code is loaded into and executed by a computer, the computer becomes a device for practicing the embodiments.
  • Embodiments can also be in the form of computer program code, for example, whether stored in a storage medium, loaded into and/or executed by a computer, or transmitted over some transmission medium, loaded into and/or executed by a computer, or transmitted over some transmission medium, such as over electrical wiring or cabling, through fiber optics, or via electromagnetic radiation, wherein, when the computer program code is loaded into an executed by a computer, the computer becomes an device for practicing the embodiments.
  • the computer program code segments configure the microprocessor to create specific logic circuits.
